Recoup with data dedupe
8 products that can help cut your storage costs through data duplication
Compellent Storage Center (Dell)
Compellent Storage Center was not really tested as part of this review, but it is instructive in another way that deduplication can be used in a SAN system. The two volumes used to test the seven other systems were stored on a Compellent SAN. The two volumes represented snapshots of a production volume taken automatically by the system about four months apart. Some 4,552 files, occupying 31.7GB of space, were changed or added to the volume. The two snapshots actually stored only changes to the data on the system — the total space used by both snapshots was not 589GB each, but only about 32GB, representing the changes made to the volume.
